l SIFTER CAP.

Application filed March 24, 1921. Serial No. 455,097'.

To all whom t may concern.'

Be it known that l, JoHN M. HoTHnnsALL, a citizen of the United States, residing in Brooklyrnin the county of Kings and State of New York, have invented a new and useful linprovement in Sitter Caps, of which the following is a specification.

This invention relates in general to container closures and more particularly to covers for sifter tops such as are commonly employed upon talcum powder boxes and the like.

principal object of the invention is the provision of a cover of' this type adapted to be position-ed upon the container without the employment of any threads or other difficult ineans of attachment and at the same time to provide a closure adapted to remain firmly in place even when subjected to rough usage, as in transit.

Another object of the invention is to provide a closure of this type which presents a pleasing appearance and which is so formed as to have sullicient resilience to cause it to remain in place witl'iout the use of any separate locking means.

A. still further object of the invention is the provision of an article of this character which is easily constructed and capable of practical production as an article of manufacture without adding materially to the cost of the container.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description when considered in connection with the accompanying drawings illustrating a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is an elevational view of a talcum powder box of the type upon which my invention is adapted to be employed, a closure embodying the invention being shown detached;

l? ig. 2 is an enlarged vertical section of the top portion of the box with the cover in place;

Fig. 3 is a side elevation of the detached closure; and

Fig. 4 is a bottom View thereof.

@n the drawings which illustrate an enrV bodiinent of my invention l have shown a container for talcum powder and the like, having a body portion 11 and a sifter top tainer body. ln this sitter top are perforations 13, the perforated portion being raised from the body of the can by a straight-4 walled neck 14.

lt will be manifest that the design of the container, upon which the invention is employed, may vary widely and that the sifter top may be of any preferred type and may be variously arranged.

l provide a cap 16 having a depending scalloped flange 17 adapted to engage the neck 14. The flange is scalloped as indicated at 1S and there are slits 18 in the material between the scallops 19 for the purpose of providing resilience, whereby said cap is caused to stay permanently in place upon the neck, covering tlie sifter top and engaging tightly the outer portion thereof, whereby escape'of powder or other contents is prevented and the material inthe container is protected from foreign matter. The eX- tremities of the scallops 19 are outwardlyv turned or flared as at 19 to permit easy positioning upon the sifter top.

The cap 16, as may be seen by reference to Fig. 2, is formed with a bulge or bead 15 about its periphery and there is an indentation or groove 15 extending about the top of the cap just above said bead. In the space between the perforated portion of said sifter top and the domed part of the cap is provided a packing or gasket 21. While its design may vary and yet embody the principle of my invention, I lind it to be advantageous both from the standpoint of effectiveness and appearance to slightly bulge the portion 15 of the flange at the points of termination of the slits 18', said points being indicated by the numeral 22, thus giving said flange a polygonal configuration. Tight engagement of the depending flange 17 upon the neck 14 of the container caused by the scalloping of said flange, makes inadverteinl removal practically impossible, the cap which l provide, therefore, being extremely effective as a mechanical device.

t is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form herei-nbefore described being merely a preferred embodiment thereof.

I claim:

1. In a si-liter can for talcum powder and the like the combination `of a body haring a straight-walled neck formed with a perforated sitter top, a cap conforming with said top and bulged out at the sides of the neck and thence bent inward, downward and outward to form `a rounded bearing on the wall of the neck, and a gasket compressed between the cap `and said top and extended outward past the top corner of the neck, said top being formed with an indentation ,or groove 15 extending around the top of the' cap opposite to said corner of the neck and between which and said corner the gasket is conined.

2. The combination ,of fa can having a perforated top and a substantially straight and smooth-walled neck, and a cap comprising a solid domed top portion and a bulged lcpending flange having its lower parts scalloped and having a plurality of slits about its periphery, said bulge, scallops and slits forming a spring member `which ypermits said cap lto make frictional contact with the neck of a box, to be easily removed and repeatedly reapplied without losing its original shape.

3. The combination of a can having: a perforated top and a substantially straight and smooth-walled neck, and a cap comprising a solid domed top portion and a slit depem'ling iange, said flange being scalloped and outwardly turned at its extremity and being slightly flexed when in t'rictional Contact with the object to be closed and adapted to return to normal position when removed from said object, thereby making.T said cap adapted for repeated use.
